Police say 68 people were arrested during the scuffle. At least one person was accused of assaulting a police officer, who suffered cuts on one hand. Other charges include trespassing, disorderly conduct and reckless endangerment.

Protester Jason Amadi says he was pepper-sprayed when police tried to prevent the crowd of about 500 demonstrators from taking down the barricades. Amadi says the crowd piled the barricade pieces in the center of the park and stood on top of them, chanting and singing.

Police are still processing arrests but say some protesters have been released. No other details were available Sunday.
